SULLIVAN, of a ring-spinningmachine provided with my of New Bedford, in the county of Bristol andimprovement, the central portion being' cut State of Massachusetts, haveinvented a new out to reduce the length of the drawing.

The curtain l forms a flexible yielding surface along therear of uthe row of spindles and sufficiently close to the same toprevent the excessive ballooning of the yarn and the interference of theyarn of adjacent spindles.

In practice I iind that it requires one or more turns of a spindle, evenat the highest speed, to exert sufficient centrifugal force on the yarnto cause it to bow outward or balloon perceptibly and that the yarn bycoming in contact for a considerable length at each revolution with thesurface of the curtain 15 does not acquire sufficient centrifugal forceto bow outward or balloon so as to come in contact with the yarn of theadjacent spindle. I further find that the spindles may be placed closertogether than is now customary without the yarns of the adjacentspindles interfering with each other even at a higher speed than is nowgenerally used.

Consequently the number of spindles in a ma chine may be increased aswell as the speed and a corresponding increase in the productionsecured.

It is also obvious that the curtain 15, whether fixed or rolling,prevents oats from being carried in between the spindles from the frontand limits the ballooning of the yarn.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent- 1. In aring-spinning machine, the combination with the spindles, thereciprocating rin g-rail, of a curtain secured to the rin g-rail, and aself-windin g curtain-roll supporting the upper part of the curtain andlocated in a plane above the ring-rail, whereby the yarn is protectedagainst floats and excessive ballooning, as described.

2. In a ring-spinning machine, the combination with the front beam andthe ring-rail of the machine, of the roller 16 supportedin suitablebearings above the highest reciprocation of the ringrail, a curtainsecured to the roller as described, for automatically rolling up andletting out the curtain, whereby the space between the ring-rail and thefront beam is closed by the curtain.

3. In a ring-spinning machine, the combination with the spindles, thereciprocating ring-rail and the front beam of the roller 16, the cord18, the weight 19 and the curtain 15 secured to the roller and to thering-rail, whereby the curtain is automatically adjusted to close thespace between the ring-rail and the front beam, as described.

In witness whereof I have hereunto set my hand.
